How to divide values to several columns

Question

Hi
I have a table including values that I want to display in 5 columns.
Table structure is:
Use_id number (primary key)
target id number
code number
Values in a table are:
1 234 22
2 345 23
3 564 24
4 634 25
5 345 24
6 545 22
7 234 23
8 634 23
I want to select (display) the values like:
target_id code22 code23 code24 code 25
234 22 23
345 23 24
564 24
634 23 25
545 22
Is it possible to create a view for that purpose?

If you know the different possible codes in advance, you can try something else like below :
SQL> create table mytable (Use_id number primary key,
  2  target_id number,
  3  code number);
Table created.
SQL>
SQL> insert into mytable
  2  select 1, 234, 22 from dual union all
  3  select 2, 345, 23 from dual union all
  4  select 3, 564, 24 from dual union all
  5  select 4, 634, 25 from dual union all
  6  select 5, 345, 24 from dual union all
  7  select 6, 545, 22 from dual union all
  8  select 7, 234, 23 from dual union all
  9  select 8, 634, 23 from dual ;
8 rows created.
SQL>
SQL> create or replace view myview
  2  as select target_id,
  3            max(decode(code,22,code)) code22,
  4            max(decode(code,23,code)) code23,
  5            max(decode(code,24,code)) code24,
  6            max(decode(code,25,code)) code25
  7  from mytable
  8  group by target_id;
View created.
SQL>
SQL> select * from myview;
TARGET_ID     CODE22     CODE23     CODE24     CODE25
       234         22         23
       345                    23         24
       545         22
       564                               24
       634                    23                    25
